Sayyiduna Anas (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) was leading the prayer. During this, a man came whose breath was short. He said: "All praise is exclusively for Allah, such praise that is abundant, pure, and blessed." When the Prophet Muhammad (peace and blessings be upon him) completed his prayer, he inquired: Who is the person who uttered these words? The people remained silent. He asked again: Who is the person who said these words? He has not said anything bad. The man submitted: O Messenger of Allah! It was me. When I came, I was out of breath, so I said these words. The Prophet Muhammad (peace and blessings be upon him) said: I saw twelve angels rushing towards them, as to who would take them up.
